"""Smoke tests for the batch-extracted subcommand parser builders.

Each ``build_<group>_parser`` should attach its subcommand to a subparsers
group and wire ``func`` to the injected handler. These are intentionally
light — the byte-identical ``--help`` verification done at extraction time is
the real behavioral guarantee; this just guards against a module failing to
import or a builder raising.

# ── deprecated `hermes login` fails gracefully, not with argparse error ────
#
# `hermes login` is a removed command; its handler (`login_command` in
# `hermes_cli/auth.py`) prints a deprecation notice pointing at `hermes auth` /
# `hermes model` and exits 0.  Two behavior contracts guard the UX:
#   1. ANY `--provider <value>` (including ones the user actually wants, like
#      `anthropic`) must parse and reach the handler — never crash in argparse
#      with `invalid choice` before the friendly redirect is printed (#24756).
#   2. The subcommand must not advertise itself in the parser help row.
